A family office can oversee a portfolio to the basis point yet be exposed on a yacht and a jet it never trained to run. The governance gap is quiet, expensive, and entirely closable.
The family office reconciles the investment book to the cent, but the £40m yacht and the long-range jet sit in a blind spot: invoices arrive in three currencies, the captain and the aviation manager answer to no one in particular, and no member of the team has ever run a marine or aviation budget. The assets that generate the loudest complaints and the largest cash calls are the two nobody in the office was hired to govern.
A family office is built for capital: managers, custodians, tax counsel and reporting lines are chosen for financial rigour. Yachts and jets are different animals. They are operating businesses with payroll, regulators, physical depreciation and safety liability, run in industries the office has no native expertise in. The principal assumes the office is watching; the office assumes the captain and the aviation manager have it in hand. Neither is quite true, and the gap sits precisely where the money moves fastest.
The consequence is not usually fraud in the first instance — it is drift. Budgets are set by the people who spend them. Contracts renew unread. A refit or an engine event lands as a surprise cash call because no one was tracking the maintenance runway. Charter income, where the asset earns, arrives net of deductions the office cannot itemise. Each of these is a small failure of oversight, and none of them announces itself; they simply accumulate on the far side of a wall the office never meant to build.
The office is capable of governing these assets to the same standard as the portfolio; it simply lacks the marine and aviation fluency to ask the right questions. That fluency, not more headcount, is what closes the gap. It is the difference between receiving a management report and interrogating it — between accepting a €180,000 yard estimate and knowing which lines in it are soft — and it is the single most valuable thing an independent adviser brings to the table.
Mobile assets resist tidy reporting. A yacht bills through a management company, a fuel supplier, a shipyard and a crew agency; a jet bills through an operator, an FBO network, maintenance vendors and insurers. Statements arrive on different cycles, in different currencies, against budgets nobody built from first principles. The office ends up paying invoices it cannot benchmark, because it has nothing to benchmark them against.
Real control starts with an owner's budget the office actually owns — built bottom-up, line by line, and reconciled monthly against a single consolidated statement across both assets.
Reporting of this kind converts two opaque cost centres into two managed ones, and gives the office the evidence to challenge any figure on the page.
Mobile assets are unusually exposed to leakage because spending authority sits far from the office, often on the far side of the world and in cash-heavy environments. A captain or aviation manager who controls procurement, approves invoices and selects suppliers holds every lever at once. Most loss is not dramatic embezzlement; it is undisclosed supplier commissions, marked-up provisioning, inflated yard hours and comfortable relationships that never go to tender. A rebate of a few per cent on fuel here, a kickback on a refit there, a provisioning account that runs ten per cent hot — left unchecked, it compounds quietly into six figures a year on a large yacht.
Oversight is a controls problem the office already understands from its financial operations, applied to unfamiliar ground. It rests on a handful of disciplines.
None of this impugns an honest captain — a well-run boat welcomes the scrutiny because it clears their name — but it removes the conditions in which leakage thrives and gives the office documented assurance rather than blind trust in a single individual holding all the keys at once.
Beyond the money sits a stack of obligations the office is rarely staffed to carry. Crew are employees under flag-state and Maritime Labour Convention rules, with contracts, payroll, rotation, medical cover and duty-of-care that a family cannot improvise without inviting a claim. Aviation crew carry their own currency, recurrent training and duty-time regimes, and a lapsed type rating or an exceeded flight-time limit grounds the aircraft on the day it matters. Compliance is unforgiving on both assets: a yacht must satisfy its flag administration and classification society, a jet its aviation authority, and a missed survey or certificate does not merely risk a fine — it stops the asset moving and can void the insurance behind it.
Insurance is where thin oversight becomes catastrophic. Hull, protection-and-indemnity, liability and crew cover must match how the asset is actually used — charter versus private, declared cruising or operating area, named captain — or a claim is denied at the worst possible moment. Ownership structure ties it all together: the holding vehicle, flag and import position determine tax exposure, VAT treatment, liability ring-fencing and the privacy the family expects, and a structure built for private use quietly fails the day the asset is chartered. These threads are interdependent — a change of use ripples through crew status, insurance and tax at once — and governing them demands marine and aviation fluency the standard family-office team simply does not carry in-house.
The value of specialist governance is easiest to see laid out as a grid. Each oversight area carries a characteristic risk when left to the people who operate the asset, and a corresponding control the office can put in place.
| Oversight area | Risk if left unmanaged | Governance solution |
|---|---|---|
| Budget & reporting | Budgets set by those who spend them; surprise cash calls | Owner-built bottom-up budget, monthly consolidated variance reporting |
| Vendor & procurement | Undisclosed commissions, marked-up provisioning, sole-sourcing | Separation of duties, competitive tender, contract and expense audit |
| Crew & payroll | Non-compliant contracts, duty-of-care and rotation failures | MLC-compliant employment, managed payroll, verified currency and training |
| Compliance | Flag, class or aviation-authority lapse grounds the asset | Tracked certificate and survey calendar with forward alerts |
| Insurance | Cover mismatched to use; claim denied when it matters | Independent review of hull, P&I, liability and crew cover against actual use |
| Ownership & tax | Structure built for one use fails; VAT and liability exposure | Holding, flag and import structure reviewed against current use and law |
Read as a whole, the grid makes the point plainly: every line is a place where financial rigour already lives in the office and needs only marine and aviation fluency to reach the asset.
None of this argues for replacing the family office — it argues for equipping it. The office keeps the relationship with the principal, the reporting lines and the final authority; the specialist supplies the domain fluency the office was never built to hold and the independence that in-house managers structurally cannot. An adviser who takes no supplier commission and holds no operational role can benchmark a yard quote, read an insurance wording or interrogate a fuel bill without a conflict, because they answer only to the owner.
Obsidian Helm occupies exactly that seat: an independent adviser working alongside the family office, not competing with it. We bring the marine and aviation questions the office cannot, review the reports it receives, tender the contracts it signs and give the principal a single informed view across both assets. The office keeps control; it simply gains the expertise to exercise it. That is the whole of the proposition — not another manager to pay, but the fluency that makes the managers accountable.
We act as the family office's independent adviser on its yacht and jet, sourcing and vetting managers, captains, crew and insurers through the Obsidian Helm Marketplace network under NDA, tendering major yard and maintenance work, and reconciling both assets to one consolidated figure. We take no supplier commission and hold no operational role — so we can benchmark every quote and challenge every invoice, answering only to you.

A family office is built for financial assets, not operating businesses with crew, regulators and physical depreciation. Yachts and jets demand marine and aviation fluency the standard team does not carry, so budgets get set by those who spend them and contracts renew unread. Specialist oversight closes that governance gap without adding a manager the office must pay.
Both assets are mapped to a common chart of accounts, so multi-currency costs from operators, yards, crew agencies and insurers roll up into one statement in the family's reporting currency. Every material line is tracked against a bottom-up budget, with variances flagged monthly and major cash calls such as refits and overhauls forecast years ahead.
Most loss is quiet: undisclosed supplier commissions, marked-up provisioning and sole-sourced renewals rather than outright theft. Controls mirror financial best practice — separating who spends from who approves, tendering major yard and maintenance work competitively, reading contracts for hidden commission clauses, and auditing provisioning and fuel against benchmarks. It gives documented assurance rather than blind trust in one person.
No. The adviser complements the family office and any operational managers, supplying the marine and aviation fluency and the independence that in-house staff structurally cannot. The office keeps the principal relationship and final authority; the adviser interrogates reports, tenders contracts and benchmarks quotes without conflict, because they take no supplier commission and answer only to the owner.
The holding vehicle, flag and import position determine tax exposure, VAT treatment, liability ring-fencing and privacy. A structure built for private use can fail the moment the asset is chartered, and insurance mismatched to actual use sees claims denied. Reviewing structure and cover against how the asset is genuinely used is core to protecting the family.
